The bottom-up synthesis of graphene nanoribbons (GNRs) offers a promising approach for designing atomically precise GNRs with tuneable photophysical properties, but controlling their length remains challenge. Herein, we report an efficient synthetic protocol producing length-controlled armchair (AGNRs) through living Suzuki-Miyaura catalyst-transfer polymerization (SCTP) using RuPhos-Pd catalyst and mild graphitization methods. Initially, SCTP dialkynylphenylene monomer was optimized by...
Despite the high potential of one-dimensional (1D) donor-acceptor (D-A) coaxial nanostructures in bulk-heterojunction solar cell applications, preparation such 1D using π-conjugated polymers has remained elusive. Herein, we demonstrate first example D-A semiconducting nanoribbons based on fully conjugated block copolymers (BCPs) prepared a highly efficient procedure with controllable width and length via living crystallization-driven self-assembly (CDSA). Initially, Suzuki-Miyaura...
Self-assembly of conjugated polymers offers a powerful method to prepare semiconducting two-dimensional (2D) nanosheets for optoelectronic applications. However, due the typical biaxial growth behavior polymer self-assembly, independent control width and length 2D sheets has been challenging. Herein, we present greatly accelerated crystallization-driven self-assembly (CDSA) system polyacetylene-based produce nanorectangles with precisely controllable dimensions. In detail, rectangular seeds...
We present a simple drop-casting method for preparing multiferroic nano-composite film where BiFeO3 (BFO) nanoparticles (NPs) were evenly dispersed into polyvinyl alcohol (PVA) polymer. BFO NPs used in this work synthesized by the conventional sol-gel method, having diameter of tens nm and being good crystallinity. The loaded highly insulating PVA polymer solution as filler. properties reveal ferromagnetic ordering due to uncompensated spiral saturated ferroelectric curves cut-off current...
Living polymerization has played a pivotal role in producing conjugated rod–coil block copolymers, offering means to harness the functions of two distinct materials within nanoscale regions. Nevertheless, accessibility diverse array such copolymers been restricted, primarily due lack an efficient synthetic approach. To address this issue, we developed bifunctional initiator approach that integrates versatile living polymerizations: atom transfer radical (ATRP) and Suzuki–Miyaura...
This study used lenses made using 2-hydroxyethyl methacrylate (HEMA), a basic material for hydrogel lenses, ethylene glycol dimethacrylate (EGDMA), and an initiator 2,2'-Azobis (2-methylpropionitrile) (AIBN). A combination of the hydrophilic additives N, N-Dimethylacrylamide (DMA), N-vinyl pyrrolidone (NVP), methacrylic acid (MA), nanomaterial Bismuth (III) oxide was added to prepare Comparative group lens. As result measuring change in physical properties produced contact lens, water...
